WHEREAS, Portland Parks and Recreation encourages, supports, and contributes to the development of greenspaces, greenways and urban treescapes that directly enhance the City's environment and residents' quality of life; and

WHEREAS, City Council and the Portland Development Commission have adopted Green Building Policies which support incorporating sustainable and green building practices in all projects with specific requirements for City-owned buildings and projects receiving public funding or financial incentives; and

POLICY

NOW, THEREFORE, BE IT RESOLVED, that the City Council affirms the City Council's intent to manage stormwater as a resource through the use of green infrastructure techniques using onsite surface vegetated facilities to the greatest extent possible.

BE IT FURTHER RESOLVED, to support the intent and application of Portland's Stormwater Management Manual, City capital improvement projects other than construction or replacement of underground sewer and water system infrastructure shall manage stormwater through an onsite surface vegetated facility as a first priority. Any City of Portland project that a City bureau or department intends to construct outside the right-of-way without using this approach must receive approval for an alternative method of stormwater management through City Council action unless it is within an established exemption category specified by the Stormwater Manual or City Council. Projects in which PDC contributes $300,000 or more for capital improvements are subject to this policy.

Surface vegetated facilities should also be used in the right-of-way whenever technically feasible, in accordance with the Stormwater Management Manual's stormwater hierarchy.

BE IT FURTHER RESOLVED, this the policy contained in this resolution shall be binding City policy and filed in the Portland Policy Documents Repository as such.
